DESCRIPTION OF EMBODIMENTS

In the following detailed description, reference is made to the accompanying drawings that show, by way of illustration, various embodiments of an invention. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that the various embodiments of the invention, although different, are not necessarily mutually exclusive. For example, a particular feature, structure, or characteristic described in connection with one embodiment may be implemented within other embodiments without departing from the scope of the invention. In addition, it is to be understood that the location or arrangement of individual elements within each disclosed embodiment may be modified without departing from the scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims, appropriately interpreted, along with the full range of equivalents to which the claims are entitled. In the drawings, like numerals refer to the same or similar functionality throughout the several views.

FIG. 3 shows a mobile device in accordance with various embodiments of the present invention. Mobile device 300 includes a touch sensitive display device 302 that is shown displaying a desktop screen 310. Touch sensitive display device 302, in combination with processing circuits coupled thereto, detects gestures made by a user while touching device 302. For example, a human hand is shown making one of many gestures on touch sensitive display device 302.

Mobile device 300 may be any mobile device that includes multiple desktop screens navigable by gestures. Examples include, but are not limited to, mobile phones, tablet computers, personal digital assistants, and the like.

Mobile device 300 may detect multiple different types of gestures. For example, mobile device 300 may detect a first gesture 312 used to navigate between non-password protected desktop screens and may detect a second gesture 314 used to navigate from a non-password-protected desktop screen to a password protected desktop screen. This is described in more detail below.

Mobile device 300 is capable of displaying multiple desktop screens. Desktop screens on mobile device 300 display content such as application icons, widgets, and the like. Application icons that display on desktop screens are used to launch applications. For example, a user might launch a music player application by tapping on icon 330. Also for example, the user might launch an email application by tapping on icon 332. Both application icons 330 and 332 are displayed on desktop screen 310.

In some embodiments, mobile device 300 displays desktop screen indicator 320 to provide a visual indication of the desktop screen currently being displayed. Additional desktop screen indicator embodiments are described further below.

A user may navigate between desktop screens using gestures. For example, a user may navigate between desktop screens that are logically oriented side-by-side by using a swipe gesture from left-to-right or from right-to-left such as gesture 312. Referring now to FIG. 4, desktop screen 310 is shown logically oriented with desktop screen 410 to the left and desktop screen 420 to the right. A user may navigate from desktop screen 310 to desktop screen 410 by entering a left-to-right swipe gesture 312. The user may also navigate from desktop screen 310 to desktop screen 420 by entering a right-to-left swipe gesture 312.

Desktop screens 410, 310, and 420 are examples of non-password-protected desktop screens. The user may freely navigate between these desktops screens without any additional layers of authentication. When the user gestures to navigate between the non-password-protected desktop screens, the non-password protected screens display without any additional input from the user.

In addition to non-password-protected desktop screens, mobile device 300 includes at least one password protected desktop screen 450. A user may navigate from a non-password-protected desktop screen (e.g., 310) to a password protected screen (e.g., 450) by gesturing with gesture 314. When mobile device 300 recognizes gesture 314 while displaying a non-password-protected desktop screen, the mobile device requires an additional layer of authentication prior to navigating to the password protected desktop screen. This is described further below.

Although gesture 314 is shown as a vertical swipe gesture, this is not a limitation of the present invention. For example, gesture 314 may be non-vertical, or may be something other than a single swipe. In some embodiments, gesture 314 requires multiple movements, such as connecting imaginary dots in sequence on touch sensitive display device 302.

Desktop screens 310, 410, 420, and 450 are all desktop screens that display application icons and other content. For example, applications may be launched using icons that are displayed on any of desktop screens 310, 410, 420, and 450. Further, a user may navigate between all of the desktop screens using gestures, although further authentication may be required when navigating from a non-password-protected desktop screen to a password protected desktop screen.

In some embodiments, applications may be launched from icons on desktop screens, and may also be launched using other mechanisms provided by mobile device 300. For example, an applications folder may be provided in a directory structure accessible via menus, and the application folder may also display icons that allow applications to be launched. In some embodiments, applications may only be launched from desktop screens. For example, applications that are installed to password-protected desktop screens may only be accessible from those desktop screens. This prevents unauthorized access to those applications.

In some embodiments, password protected desktop screens display application icons that are grouped in categories. For example, financial applications may be installed on one password protected desktop screen or one set of password protected desktop screens. Also for example, applications that hold other sensitive documents or data may be installed on one password protected desktop screen or one set of password protected desktop screens. Example password protected desktop screens are described below as “wallet desktop screens” that control access to finance related applications, but this is not a limitation of the present invention. Access to any type of application may be controlled through password protected desktop screens without departing from the scope of the present invention.

Desktop screens and the logic that interprets gestures are part of a user interface component within mobile device 300. The user interface component may include many other elements, including for example, menus, feedback devices (audio, haptic, etc.) window managers, file managers, and the like. The user interface component is described in more detail below with reference to FIG. 11.

FIG. 5 shows a password protected desktop screen prompting for a password in accordance with various embodiments of the present invention. Mobile device 300 prompts for a password when a gesture is recognized that attempts to navigate from a non-password-protected desktop screen to a password-protected desktop screen. As shown in FIG. 5, a mobile wallet desktop screen may be password protected, and mobile device 300 prompts for the password when a gesture is recognized that attempts to navigate to the mobile wallet desktop screen.

Note that the desktop screen indicator 520 has changed to signify the location of the password protected mobile wallet desktop screen 450 in the logical orientation shown in FIG. 4. After the user enters the password and it is validated, then the navigation to the password protected mobile wallet desktop screen is allowed. An example mobile wallet desktop screen is shown in FIG. 6.

In some embodiments, the password is validated using software within mobile device 300, and in other embodiments, the password is validated using hardware within, or coupled to, mobile device 300. For example, the password may be routed to a smartcard secure element for validation. The smartcard secure element may be in any location, including within mobile device 300, on a card in an add-on slot of mobile device, or in communications with mobile device over a contactless interface. Cards in add-on slots may or may not be removable. For example, a memory card may be user accessible and removable, or may be embedded deep within the mobile device to provide system memory, and nonremovable. Smartcard secure elements and their various possible locations are described more fully below. In some embodiments, passwords may be alphanumeric only, and in other embodiments, passwords may be numeric only and yet in others it may include special characters.

As used herein, the terms “password protected” and “non-password-protected” refer to different levels of authentication required to access different desktop screens. These different levels of authentication may coexist with further levels of authentication in the mobile device. For example, an “unlock” feature of mobile device 300 may require a user to enter a password, a gesture, or the like. The user unlocks the mobile device by authenticating to the mobile device using the password or gesture required for the unlock feature. Once the mobile device is unlocked, the non-password-protected desktop screens may be accessed without further authentication, whereas the password protected desktop screens may require further authentication as described above. Accordingly, the password protection used to lock the mobile device is different from the additional authentication used when navigating from a non-password protected desktop screen to a password protected desktop screen.

The example of FIG. 5 shows a password mechanism providing an additional level of authentication, although this is not a limitation of the present invention. For example, a user may be allowed to navigate to the password protected desktop screens when an additional hardware token is present (e.g., microSD card, USB dongle, Bluetooth device, NFC device). In these embodiments, the token provides the additional level of authentication, and a password may not be required. In other embodiments, the additional level of authentication may be provided by bioinformation (e.g., fingerprint, face recognition, iris scan, etc.). In still further embodiments, a challenge question and response mechanism may be used to provide the additional level of authentication. Any authentication mechanism may be employed without departing from the scope of the present invention.

Although two applications are shown installed on password protected desktop screen 450 in FIG. 5, this is not a limitation of the present invention. Any number of applications may be installed to a password protected desktop screen, including zero, one, or more than one.

FIG. 6 shows a password protected desktop screen displaying mobile wallet applications in accordance with various embodiments of the invention. Mobile device 300 is shown displaying icon 602 for a mobile payment application “Bank 12 Credit Card” and icon 604 for a mobile banking application “Bank 42 Mobile Banking.” In the example of FIG. 6, these two applications are grouped together as financial applications and are installed to the same password protected desktop screen.

In some embodiments, applications launched from mobile wallet desktop screen 450 do not require further authentication beyond the authentication necessary for the user to reach the mobile wallet desktop screen. This provides a level of convenience to a user that wishes to open multiple financial applications without entering a password for each one. The user can authenticate to the mobile wallet desktop screen once, and then select which mobile wallet application to open, or even open multiple mobile wallet applications without further authentication.

FIG. 7 shows a screenshot of a financial application in accordance with various embodiments of the present invention. FIG. 7 shows mobile device 300 displaying the Bank 12 Credit Card application. This application is launched from mobile wallet desktop screen 450 (FIG. 6) by tapping icon 602. In the embodiment of FIG. 7, no additional authentication (beyond the authentication necessary to navigate to wallet desktop screen 450) was necessary for the user to launch Bank 12 Credit Card. The Bank 12 Credit Card application is an example of a mobile payment application that allows a user to make credit card payments using a credit card issued by Bank 12.

As shown in FIG. 7, the mobile payment application may display information specific to an application provider (e.g., branding information 702), information specific to a user (e.g., available credit information 704), and mobile device specific information (e.g., NFC antenna tap location information 706).

The device specific information may show any type of information. Examples related to NFC payments include showing a region on the mobile device to tap, orientation of the mobile device when tapping, whether to tap on the front or back of the mobile device. Further, this information may be color coded, or maybe dynamic content that changes shape, color, or text, in response to user actions. For example, the TAP HERE icon shown in FIG. 7 may change size or color, or may animate when a successful exchange of information over a contactless link (e.g., NFC) has occurred. In some embodiments the dynamic content could also be represented with audio or haptic feedback. In some embodiments, the mobile device specific information may be maintained in a centralized database that is updated when new mobile device models become available.

FIGS. 8 and 9 show logical orientations of multiple desktop screens in accordance with various embodiments of the invention. FIG. 8 shows non-password-protected desktop screens 410, 310, and 420. A user may freely navigate between these desktop screens without additional authentication as described above. FIG. 8 also shows multiple password protected desktop screens 810, 450, and 820. In some embodiments, a user may freely navigate between the multiple password protected screens once authenticated to them. For example, a user may authenticate to a password protected desktop screen 450 after providing a gesture 314 to navigate from a non-password-protected desktop screen 310 to password protected desktop screen 450, after which the user may freely navigate between the password protected desktop screens (e.g., 810, 450, 820) without additional authentication.

FIG. 9 shows all of the desktop screens shown in FIG. 8, and in addition shows password protected screens 910, 920, and 930. In the example of FIG. 8, password protected desktop screens 810, 450, and 820, form one logical row of password protected screens that can be navigated with gesture 312, and password protected desktop screens 910, 920, and 930 form a second logical row of password protected desktop screens that can be navigated with gesture 312.

In some embodiments, authentication to one logical row of password protected desktop screens with provide authentication to all logical rows of password protected desktop screens. For example, a user that has authenticated to password protected desktop screen 450 as described above may be able to access password protected desktop screen 920 with an additional gesture 314 without additional authentication. In other embodiments, each row of password protected desktop screens requires an additional level of authentication.

In some embodiments, rows of desktop screens may be accessed in a circular manner as shown in FIG. 9. For example, continuous gestures in one direction will repeatedly scroll through the rows of desktop screens. In other embodiments, rows of desktop screens are navigated in a noncircular manner such that if a user has navigated to the bottom-most row, the only option is to navigate up, and if the user has navigated to the top-most row, the only option is to navigate down.

FIG. 10 shows various desktop screen indicators in accordance with various embodiments of the present invention. Indicator 1000 shows two rows to indicate that the desktop screen currently displayed is in a top row of two rows. This may correspond to the display of desktop screen 450 when two rows of desktop screens exist (FIG. 8).

Various embodiments of the present invention use different desktop screen indicators. In some embodiments, the desktop screen indicators include multiple rows as shown at 1000, and in other embodiments, the desktop screen indicators include a single row with additional icons to signify the current row, or possible scroll directions. For example, indicator 1010 includes a lock icon to signify that the current row is a row of password protected desktop screens. Also for example, indicator 1020 includes a dollar sign icon to indicate that the current row is a row of mobile wallet desktop screens. In still further examples, indicators 1030, 1040, and 1050 include icons to indicate possible scroll directions. In some embodiments, multiple row indicators include additional icons. For example, indicator 1000 may include a lock icon and/or a dollar sign icon, as well as up and down arrows to indicate scroll directions. At least one row of desktop screen indicators maybe displayed at any given time.

Other application examples include applications that store an identity such as a passport or a building access identity.

Each of the above-identified applications correspond to a set of instructions for performing one or more functions described above. These applications (sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these applications may be combined or otherwise re-arranged in various embodiments. For example, telephone application 1131 may be combined with contacts application 1132. Furthermore, memory 1110 may store additional applications (e.g., video players, camera applications, etc.) and data structures not described above.

It should be noted that device 300 is presented as an example of a mobile device, and that device 300 may have more or fewer components than shown, may combine two or more components, or may have a different configuration or arrangement of components. For example, mobile device 300 may include many more components such as sensors (optical, touch, proximity etc.), or any other components suitable for use in a mobile device.

Memory 1110 represents a computer-readable medium capable of storing instructions, that when accessed by processor 1150, result in the processor performing as described herein. For example, when processor 1150 accesses instructions within user interface application 1121, processor 1150 recognizes gestures and requires additional authentication when navigating from a non-password-protected desktop screen to a password protected desktop screen.

Further, in some embodiments, some actions listed in FIG. 22 are omitted from method 2200.

Method 2200 begins at 2210 in which a user interface is displayed on a touch sensitive display device. The user interface includes a plurality of non-password-protected desktop screens and at least one password protected desktop screen. Examples of logical orientations of non-password protected desktop screens and password protected screens are shown in FIGS. 4, 8, and 9. The remaining portion of method 2200 is described with the desktop screens in FIG. 4 as examples; however, method 2200 is equally applicable to any logical orientation of desktop screens.

At 2220, a gesture is detected at the touch sensitive display device. The gesture may be a gesture used to navigate between desktop screens, such as gesture 312 or gesture 314 (FIG. 3). At 2230, the gesture is analyzed to determine if it is used to navigate from a non-password-protected desktop screen to a password protected desktop screen. If not, then the navigation to the non-password protected desktop screen takes place without additional authentication at 2270. If, on the other hand, the gesture is recognized as one that will navigate from a non-password-protected desktop screen to a password protected desktop screen, method 2200 prompts for a password at 2240. An example screenshot of a password prompt in accordance with 2240 is shown in FIG. 5.

At 2250, the password is verified. In some embodiments, this includes accessing a secure element such as secure element 1164. The password may be passed to secure element 1164 and secure element 1164 determines the validity of the password. In other embodiments, the password is verified without accessing the secure elements. When the password is verified, the user interface navigates to a password protected desktop screen at 2260.

Method 2300 is not limited by the type of system or entity that performs the method. The various actions in method 2300 may be performed in the order presented, in a different order, or simultaneously. Further, in some embodiments, some actions listed in FIG. 23 are omitted from method 2300.

Method 2300 begins at 2310 in which an application is analyzed as it is being installed on a mobile device to determine which mobile device services are utilized by the application when running. In some embodiments, the application is analyzed to determine which application programming interfaces (API) are accessed. In other embodiments, the application is analyzed by interpreting information supplied with the application. For example, application installation location information supplied with the application may be provided by a certification authority of an application developer.

At 2320, the application is installed to a password protected desktop screen of the mobile device based on the results of the analyzing that occurs at 2310. For example, in some embodiments, if the application being installed accesses secure element APIs, then the application is deemed to use services provided by the secure element, and the application is installed to a password protected desktop screen. The password protected screen to which the application is installed is one of a plurality of desktop screens, not all of which are password protected. For example, the application may be installed to password protected desktop screen 450 (FIG. 4).
